Pre-embedded ground wire pile

The invention provides a pre-embedded ground wire pile. The pre-embedded ground wire pile comprises a protection cover, a pre-embedded ground wire pipe, a ground wire clamp, and branch ground wire drill rods. The ground wire clamp is fixed inside the pre-embedded ground wire pipe, the branch ground wire drill rods are connected with branch ground wire pipes at the lower end of the pre-embedded ground wire pipe, the protection cover covers the upper end of the pre-embedded ground wire pipe, and the protection cover is connected with a neck at the upper end of the pre-embedded ground wire pipe through a bayonet pin shaft at the lower end of the protection cover. According to the invention, the ground wire pile is pre-embedded in the ground, is used for mounting the ground wire for line power-off maintenance and grounding an insulating boom truck for live working, and solves the difficulty that the ground wire cannot be mounted on a cement ground when mounting the ground wire. Labour intensity of workers in mounting of grounding drill rods may be reduced, mounting of the ground wire is facilitated, meanwhile, four radial grounding drill rods are embedded into soil to form a radial grounding network, resistance is reduced, flow capacity of the ground wire is enhanced and protected, and thus, good grounding effect is realized and safety of operating workers is guaranteed.
